Three concurrent forces of the same magnitude are in equilibrium. What is the angle between the forces? Also, name the triangle formed by the forces as sides
Show Hint
For three equal forces in equilibrium, the angle between any two is $120^{\circ}$.
Updated On: May 3, 2026
- $60^{\circ}$ equilateral triangle
- $120^{\circ}$ equilateral triangle
- $120^{\circ}$ $30^{\circ}$ $30^{\circ}$ an isosceles triangle
- $120^{\circ}$ an obtuse triangle
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
For three forces to be in equilibrium, they must form a closed triangle when represented as vectors.
Step 2: Detailed Explanation:
For three forces of equal magnitude to be in equilibrium, they must be at $120^{\circ}$ to each other. When these forces are represented as sides of a triangle, they form an equilateral triangle.
Step 3: Final Answer:
The angle is $120^{\circ}$ and the triangle is equilateral.
